Re: Question for K5/K7 owners
Correct, I referred to "dust removal" operation which I triggered from the menu. I haven't had a need to do open shutter manual sensor cleaning.

There are two possible interpretations of "sensor cleaning". I think you're talking about dust removal at startup. My K-7 does not make any noise for that. But when I'm cleaning the sensor myself (with a blower), the shutter is held open, and it makes the same noise that it does during a long exposure. -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.

Re: Question for K5/K7 owners
Rob, I don't have any instruments to measure these things with. I can only re-iterate my report that for all practical purposes both K-5's that we have are silent as far as sensor cleaning cycle goes. I remember my K10d was making rather loud thumping noise in this situation but as I understand K-7 and onwards got new sensor cleaning routine. I should agree with Bill here, if it ain't broken - don't fix it. On 8/26/2013 6:05 AM, Rob Studdert wrote: On 25 August 2013 14:45, Boris Liberman wrote: Hmmm.

Re: Question for K5/K7 owners
Don't worry about the noise. Its the nature of the design. I can assure you that it doesn't cause vibration on the sensor in long exposures from experience.

Re: Question for K5/K7 owners
Thanks guys, I suspected as much, it's a very poor system design to be so noisy (electrically). There is a significant differential in the noise levels between my K5 bodies so it does bother me, you can't have noise without vibration. On 24 August 2013 00:50, P.J.

Re: Question for K5/K7 owners
My K20D makes an obvious humming/buzzing sound when making long exposures. I believe the sensor shift system isn't exactly silent. It isn't very loud however your ear has to be right next to the camera to hear it. I don't think that has changed from the K10 through k-5.
